Donald Duart Maclean (/məˈkleɪn/; 25 May 1913 – 6 March 1983) was a British diplomat and member of the Cambridge Five who were members of MI5, MI6 or the diplomatic service who acted as spies for the Soviet Union. He was recruited as a "straight penetration agent" (not a double agent) while at Cambridge by the Soviet intelligence service.

From Gresham's, Maclean won a place at Trinity Hall, Cambridge, arriving in 1931 to study modern languages. While there, he joined the Communist Party. In his second year at Cambridge, his father died, and in his last year he was recruited into Soviet intelligence by Arnold Deutsch. He graduated with a First in Modern Languages and took the Civil Service exams. At the Final Board, Maclean was asked by one of the Panel interviewing him whether he had favoured communism whilst a university student, ostensibly because the Panel knew of a trip he had taken to Moscow in his second year at Cambridge.

Maclean replied "At Cambridge, I was initially favourable to it, but I am little by little getting disenchanted with it." His apparent sincerity satisfied members of the Panel, which included a family friend, Lady Violet Bonham Carter.

In 1934, Maclean started work at the Foreign Office in London. While there, he was under the operational control of GPUrezident, Anatoli Gorsky. Gorsky, who was appointed in 1939 after the entire London rezidentura was liquidated, used Vladimir Borisovich Barkovsky, a recent graduate of Moscow's Intelligence School as the case officer for Maclean.

In 1937, Maclean was put "on ice" by his Russian contact. At meeting after meeting nobody turned up. Then Kitty Harris arrived in place of his usual controller and gave the recognition phrase. "You hadn't expected to see a lady, had you?" she said. "No, but it's a pleasant surprise," he replied. Maclean would visit Harris's flat in Bayswater after work, with documents to photograph. Over the next two years, 45 boxes of documents were photographed and sent to Moscow. "She was a cut-out between Maclean and his KGB controller," said Geoffrey Elliott, who wrote a book about her with Igor Damaskin, a former KGB officer.[3]

While at the Foreign Office in London and then in the British Embassy in Paris Maclean kept Moscow informed in regard to relations between Germany and the British Empire, on the one hand, and Britain and France on the other, as Germany and France worked to end the alliances between the Soviet Union and Czechoslovakia and France in the run-up to Munich. He also kept Moscow informed about the development of Anglo-French plans for intervention in the war between Finland and the Soviet Union. [4] In Paris Maclean met Melinda Marling. The daughter of a Chicago oil executive, her parents had divorced when she was a teenager, her mother moving to Europe. In October 1929, Melinda and her sisters went to school at Vevey, near Lausanne, where their mother rented a villa, and spent their holidays at Juan-les-Pins in France.[5] Melinda Marling's mother moved to New York, marrying Charles Dunbar, an executive in the paper industry, and brought her daughters to live with them in Manhattan, where Melinda Marling attended the Spence School. After graduation she spent some months in New York City then returned to Paris, where she enrolled at the Sorbonne in Paris to study French literature. [6] Melinda Marling was introduced to Maclean, in the Café Flore in December, 1939, possibly by Mark Culme-Seymour. Culme-Seymour later described her as "quite pretty and vivacious, but rather reserved. I thought that she was a bit prim. She was always well-groomed, lipstick bright, hair permed, a double row of pearls around her neck. Her interests seemed limited to family, friends, clothes and Hollywood movies."[7]

In the 1950s, Culme-Seymour tracked down the exiled Macleans in Moscow, and another Melinda emerged. She told him that she knew she would be going to Russia right from the beginning, even before Maclean defected.[8]

Soviet archives confirm this view. As Maclean told Harris, on the evening he met Melinda, he saw more to her "I was very taken by her views. She's a liberal, she's in favour of the Popular Front and doesn't mind mixing with communists even though her parents are well-off. There was a White Russian girl, one of her friends, who attacked the Soviet Union and Melinda went for her. We found we spoke the same language." Maclean had told Melinda Marling about his role as a spy. He told Harris that Marling not only reacted positively, but "actually promised to help me to the extent that she can – and she is well connected in the American community".[9]

On 10 June 1940, as the German Army approached Paris, Donald Maclean and a pregnant Melinda Marling were married at the local Mairie[10] The British Embassy was evacuated and the Macleans drove south with one of Donald Maclean's colleagues. They escaped France on a small merchant ship and went to London.

Maclean continued to report to Moscow from London, where he was assigned by the British Foreign Office to work on economic warfare matters. Maclean became the Foreign Office's expert in economic warfare, civil air matters, military base negotiations and natural resources useful in the war, such as tungsten. Melinda Maclean went to New York to have her baby, which died shortly after its birth. Some weeks later she flew back to London and went to work in the BBC bookstore. The Macleans became part of the social set that circulated between the Cafe Royal, the Gargoyle club and the country house weekends of the Liberal establishment. Donald Maclean was promoted and given the prestigious assignment as Second Secretary at the British Embassy in Washington.[11]

Maclean served in Washington from 1944 to 1948, achieving promotion to First Secretary. Melinda Maclean was again pregnant, giving birth to a son in New York City. The Macleans frequently visited Melinda Maclean's mother and step-father in Manhattan and at Dunbar's country place in the Berkshires and vacationed on Long Island and Cape Cod with Mrs. Dunbar and Melinda Maclean's sisters. The Macleans became part of the liberal Georgetown social set in Washington, which included Katharine Graham, as well as participating in the diplomatic life of the city, Donald Maclean playing tennis with the Ambassador. [12]

Toward the end of that period Donald Maclean acted as Secretary of the Combined Policy Committee on atomic energy matters. He was Moscow's main source of information about US/UK/Canada atomic energy policy development. Although Maclean did not transmit technical data on the atom bomb, he reported on its development and progress, particularly the amount of plutonium (used in the Fat Man bombs) available to the United States. As the British representative on the American-British-Canadian Council on the sharing of atomic secrets, he was able to provide the Soviet Union with information from Council meetings. This gave Soviet scientists the ability to predict the number of bombs that could be built by the Americans. Coupled with the efforts of Los Alamos-based scientists Alan Nunn May, Klaus Fuchs and Theodore Hall (who had been identified but was allowed to remain at large), Maclean's reports to his NKVD controller gave the Soviets a basis to estimate their nuclear arsenal's relative strength against that of the United States and Britain. In addition to atomic energy matters, Maclean's responsibilities at the Washington embassy included civil aviation, bases, post-hostilities planning, Turkey and Greece, NATO and Berlin.[13]

In 1948, Maclean was appointed head of Chancery at the British embassy in Cairo. He was at that time the youngest Counsellor in the British foreign service. As soon as he arrived, Maclean had problems with his KGB contact, who arranged their meetings in an unsatisfactory manner. Maclean suggested that Melinda should simply pass his information to the wife of the Soviet resident at the hairdresser. "Melinda was quite prepared to do this," Modin reports.[14]

Cairo was an important post, the key to British power in the area and a central point in Anglo-American planning for war with the Soviet Union. [15] At this time Britain was the major power in the Middle East with troops in both the Canal Zone and nearby Palestine and airbases in the Canal Zone from which American atomic bombers could reach the Soviet Union. In regard to Egypt itself, British policy was one of laissez-faire or non-interference with the corruption surrounding King Farouk. Maclean disagreed strongly and felt that Britain encourage reform which alone, in his opinion, could save the country from communism. "And, except to stress its dangers, that was all I ever heard Donald say about communism." recalls Geoffrey Hoare, the News Chronicle Cairo correspondent.[16]

Maclean was considered the key official in the Cairo Embassy, specifically responsible for coordinating US/UK war planning and, under the Ambassador, relations with the Egyptian government. [17] By now, the double life was telling on Maclean. He began drinking, brawling and talking about his life as a spy. After a drunken episode which resulted in the wrecking of an American embassy staffer's apartment, Melinda told the ambassador that Donald was ill and needed leave to see a London doctor.[18] It is possible that this series of events was contrived to provide a way for Maclean to return to England as American intelligence was getting close to identifying Maclean as a Soviet agent by means of the VENONA messages. At this time Melinda Maclean was having an affair with an Egyptian aristocrat, with whom she traveled to Spain when Donald Maclean went to England.[19]

After a few months rest Maclean recovered from the troubles of his Egyptian period and Melinda Maclean agreed to return to the marriage, immediately becoming pregnant. Maclean's career did not seem to suffer from the events in Egypt. He was promoted and made head of the American Department in the Foreign Office, perhaps its most important assignment for an officer at Maclean's level. This allowed him to continue to keep Moscow informed about Anglo-American relations and planning. Meanwhile, the American and British governments were concluding that Maclean was indeed a Soviet agent, a process carefully tracked by Kim Philby in Washington.

The journalist Cyril Connolly described him vividly as he struck him in London in 1951. "He had lost his serenity, his hands would tremble, his face was usually a livid yellow ... he was miserable and in a very bad way. In conversation, a kind of shutter would fall as if he had returned to some basic and incommunicable anxiety."[20]

Maclean's role was discovered when the VENONA decryption was carried out at Arlington Hall, Virginia and Eastcote in London between 1945 and 1951. These related to coded messages between New York, Washington and Moscow for which Soviet code clerks had re-used one-time pads. The cryptanalysts working as part of the Venona project, discovered that twelve coded cables had been sent, six from New York from June to September 1944 and six from Washington in April 1945, by an agent named Gomer, The first cable sent but not the first to be deciphered described a meeting with Sergei on 25 June and Gommer's (sic) forthcoming trip to New York where his wife was living with her mother awaiting the birth of a child. This was decoded in April 1951. A short list of nine men was identified as possible Homers (Gomer is the Russian form of Homer[22]), one of whom was Maclean.[23]

The second cable on 2–3 August 1944 was a description, but not a transcript, of a message from Churchill to Roosevelt, which Homer claimed to have decrypted. It suggested that Churchill was trying to persuade Roosevelt to abandon plans for operation Anvil, the invasion of Provence, in favour of an attack through Venice and Trieste into Austria. This was typical of Churchill's strategic thinking since he was always looking for a flanking move. But it was rejected outright by both American and British generals.[24]

Shortly after the VENONA investigation began, Kim Philby, another member of the Cambridge Five, was assigned to Washington, serving as Britain's CIA-FBI-NSA liaison. He saw the VENONA material, and recognised that Maclean was Homer, which was confirmed by his KGB control. [21]

Believing that Maclean would confess to MI5, Philby and Guy Burgess decided that Burgess would travel to London, where Maclean was head of the Foreign Office's American desk, to warn him. In a series of events similar to those involving Maclean in Cairo, Burgess received three speeding tickets in a single day and assaulted a traffic cop in Virginia. The Governor complained to the British Ambassador and Burgess went back to London, in disgrace.

The Soviets were desperate for Maclean to get out, fearful that in his current state he would crack immediately under interrogation. Maclean sounded out Melinda about the defection. According to Modin, she responded: "They're quite right – go as soon as you can, don't waste a single moment."[14]

The day eventually earmarked for Maclean to make his escape happened to be his thirty-eighth birthday: 25 May 1951. He came home by train from the Foreign Office to their house in Kent as usual that evening, and soon after Guy Burgess, who had just been persuaded to get out, too, turned up. After eating the birthday supper that Melinda had prepared, Maclean said goodbye to his wife and children, got into Burgess's car and left. They drove to Southampton, took a ferry to France, then disappeared from view, sparking a media and intelligence furore. It was all of five years before Krushchev finally admitted that they were in the Soviet Union.

The following Monday, Melinda Maclean telephoned the Foreign Office to ask coolly if her husband was around. Her pose of total ignorance convinced them; MI5 put off interviewing her for nearly a week, and the Maclean house was never searched. No doubt their readiness to see her merely as the ignorant wife was enhanced by the fact that she was heavily pregnant at the time – three weeks after Donald left, she gave birth to a daughter, their third child. Francis Marling, Melinda's father, flew from New York to help. Friends in the State Department, gave him Foreign Office contacts who proved unhelpful. He returned to New York with a low opinion of Foreign Office officials. He felt then, as others felt later, that no serious effort was being made.[25]

Maclean, unlike Burgess, assimilated into the Soviet Union and became a respected citizen, learning Russian, earning a doctorate and serving as a specialist on the economic policy of the West and British foreign affairs. After a brief period of teaching English in Kuybyshev (now Samara) at a Russian provincial school, Maclean joined the staff of International Affairs in early 1956 as a specialist on British home and foreign policy and relations between the Soviet Union and NATO. He shared a small room with his new Soviet colleagues on the second floor of the journal's premises on Gorokhovsky Pereulok.[26] He also worked for the Soviet Foreign Ministry and the Institute of World Economy and International Relations. He was awarded the Order of the Red Banner of Labour and the Order of Combat. His publications for IMEMO were under the name of S. Madzoevsky. In the 1970s Maclean used his prestige with the KGB to protect members of the early dissident movement. He seems to have had some contact with Sakharov and the Medvedev brothers and shortly before his death wrote a critique of the retrograde development of Soviet society.

Melinda Maclean and their children joined Maclean in Moscow more than a year after his defection. Melinda was aware of her risks as a collaborator to her husband. Two months earlier, the Rosenbergs had sat in the electric chair for spying. But Melinda usually concealed her thoughts behind an expressionless look. "I will not admit that my husband, the father of my children, is a traitor to his country", she would say in outraged tones.[27]

The Maclean marriage came under pressure in Moscow as Donald Maclean continued to drink heavily until the mid-1960s, becoming violent when drunk. Kim Philby and Melinda Maclean became lovers during a ski trip in 1964, while Eleanor Philby, Philby's American wife, was on an extended visit to the US. Maclean found out and broke with Philby. Eleanor Philby discovered the affair on her return and left Moscow, for good. Melinda moved in with Philby in 1966, but within three years tired of him and left. She returned to her husband, and remained with him until she left Moscow for good in 1979.[14]

Melinda returned to the West, in 1979 to be with her mother and sisters; her children soon followed her. She died in New York in 2010 without saying a single word to the media.[28]

The three Maclean children all married Russians, but left Moscow to live in London and the U.S, as they still had the right to British or American passports. Fergus the eldest son enrolled at University College London in 1974, prompting a question in Parliament.[29]

In May 1970 Hodder & Stoughton published Maclean's book British Foreign Policy since Suez which he wrote for a British readership. Maclean told journalists that he set out to analyse the subject rather than to attack it, but criticised British diplomatic support for the United States in the Vietnam War. He stated that he would donate the English royalties to the British Committee for Medical Aid to Vietnam.[30] He foresaw a strengthening of British influence in the 1970s and 1980s as a result of economic recovery. Interviewed live by a BBC Radio reporter who detected a nostalgia for Britain in the book, Maclean refused to be drawn on whether he would like to return to London, for further research for his next book. Maclean was reported seriously ill with pneumonia in December 1982,[31] and was housebound after his recovery.[32]

Maclean was married to the American-born Melinda Marling in 1940. They had three children, Fergus, born in 1944, Donald, in 1946 and Melinda, in 1951.[33] In 1965, Maclean's wife began an affair with Kim Philby and went to live with him in 1966. Donald's son, Donald, married Lucy Hanna. They had a son, Donald Duart Maclean's only grandson, who resides in the UK.

Melinda Maclean lived out her years in New York.[34] She died in February 2010.

Maclean was reported to have died at the age of 69 on Friday, March 6, 1983. The report comes form the spokesperson for the Institute of World Economy and International Relations, the institute where he worked. [35]He was cremated and some of his ashes were scattered on his parents' grave in the churchyard of Holy Trinity Church, Penn, Buckinghamshire, United Kingdom.
